Description

The Evarts-class ships had an overall length of 289 feet 5 inches (88.2 m), a beam of 35 feet 2 inches (10.7 m), and a draught of 10 feet 1 inch (3.1 m) at full load. They displaced 1,190 long tons (1,210 t) at (standard) and 1,416 long tons (1,439 t) at full load.^[1] The ships had a diesel–electric powertrain derived from a submarine propulsion system^[2] with four General Motors 16-cylinder diesel engines providing power to four General Electric electric generators which sent electricity to four 1,500-shaft-horsepower (1,100 kW) General Electric electric motors which drove the two propeller shafts. The destroyer escorts had enough power give them a speed of 20 knots (37 km/h; 23 mph) and enough fuel oil to give them a range of 6,000 nautical miles (11,000 km; 6,900 mi) at 12 knots (22 km/h; 14 mph). Their crew consisted of 198 officers and ratings.^[3]

The armament of the Evarts-class ships in British service consisted of three single mounts for 50-caliber 3-inch (76 mm)/50 Mk 22 dual-purpose guns; one superfiring pair forward of the bridge and the third gun aft of the superstructure. Anti-aircraft defence was intended to consisted of a twin-gun mount for 40-millimetre (1.6 in) Bofors anti-aircraft (AA) guns atop the rear superstructure with nine 20-millimetre (0.8 in) Oerlikon AA guns located on the superstructure, but production shortages meant that that not all guns were fitted, or that additional Oerlikons replaced the Bofors guns. A Mark 10 Hedgehog anti-submarine mortar was positioned just behind the forward gun. The ships were also equipped with two depth charge rails at the stern and four "K-gun" depth charge throwers.^[4]

Construction and career

The ship was laid down as the U.S. Navy destroyer escort USS O'Toole (DE-274), the first ship of the name, by the Boston Navy Yard in Boston, Massachusetts, on 20 May 1943 and launched on 8 July 1943. O'Toole was transferred to the United Kingdom under Lend-Lease upon completion on 28 September 1943. Commissioned into service in the Royal Navy as HMS Gardiner (K478) on 28 September 1943 simultaneously with her transfer, the ship served on patrol and escort duty for the remainder of World War II.^[5]

The Royal Navy decommissioned Gardiner by October 1945^[5] after the end of the war and returned her to the U.S. Navy at the Boston Naval Shipyard on 12 February 1946. The ship was sold to the Atlas Steel and Supply Company on 10 December 1946 for scrapping. In 1947, she was resold to the Kulky Steel and Equipment Company of Alliance, Ohio, and finally was scrapped in June 1947.^[6]
